T0 all whom, it Wray concern. A

Be it known that I, THOMAS J. RICHARDS, a citizen of the United States,residingat Franklin, in the county of Venango and `State of Pennsylvania, have invented a certain new and useful Carbureting Device for Explosive- Engines, of which the following is a specification.

This invention relates to improvements in carbureting devices for explosive-engines.

Y The object of my invention is to provide a simple, cheap,- and durable apparatus that can be readily connected with an ordinary gasengine, so as to supply the gas reliably thereto, and to provide a simple and convenient means for supplying the warm air to the oil in the generator when desired for the purpose of putting it in better condition for taking the gas therefrom when said oil is heavy in cold weather and so constructing said meansthat the hotair connection between the engine and the generator can be readily disconnected when the warm air is not needed, thus enabling air of the normal temperature to be drawn into the generator and passed through the oil therein; 1 Y

A further object of the invention. is toV so construct the overflow ordischarge pipe that theoveroW-tank no air will passinto the gen.

Other objects and advantages of my invention resulting from the combination and ar rangement of the parts shown and about to be described will presently become apparent and the points of novelty will beset forth.

In the drawings, Figure l is a section of an apparatus constructed in accordance with my inventi0n,showing the same connected in the usual manner with an ordinary gas-engine. Fig. 2 is a detail broken sectional View of a part of the supply-tank and air-inlet tank, showing a direct connection between said tank and said pipe.

Referring to the drawings, the numeral l indicates the crude-oil or fluid supply tank, connected with the generator 2 by a pipe 3, the oil-supply being regulated by a cock 4 in the pipe 3. The fluid is maintained in the lower portion 0f the generator always at the same level, which is determined by an overflow-pipe 5 with a trap G, capable of holding serial No. 79,183. (No model.)

such a'column of tluid as will counteract the vacuum in the generator and prevent theadmission ot' air to said generator through said pipe. This pipe leads to an overflow-tank 6',

from which the tluid is taken and barreled or otherwise disposed of after it has passed through the generator.

The numeral 7 indicates the air-inlet pipe, through which air is drawn into the generator at or near the bottom of the column of oil in said generator by the movement of the piston of the engine, which engine is designated by lthe letter A, and after' the air passes through the oil in the usual manner and eX- tracts the gas therefrom the gas will pass from the generator through the valve-controlled opening 8 in the top thereof and through the gas-outlet pipe 9 to theignitionchamber of the gas-engine, where' it is exploded in the usual wa'y to propel the engine.

The numeral 10 designates an air-inlet pipe similar in construction and operation to the pipe 7 under ordinary conditions; but I adapt .said pipe for vconnection with a heated-air pipe 1l by means of a union 12, by which the pipes maybe readily disconnected when desired, so that air of the normal temperature can be drawn through the oil into the generator through pipe l0 when desired.V When the use of heated air is desired, the air is drawn into a sleeve 13, which surrounds the exhaust-pipe la of the engine, and this sleeve communicates with the pipe 1l, as clearly shown in the drawings. I provide at the top of the generator a valve 15,'which opens upwardly and controls the opening leading from the small chamber 16. This valve affords relief into the open air in case the explosion from the engine passes back toward the generator.

It is not necessary that the oil-supply pipe 3 should enter the generator directly, as shown in Fig. l of thedrawings,.and said pipe may be tapped directly into the air-pipe 7, so that the admixture of the oil and air would take place to some extent in .the pipe 7 and pass together into the generator.

It will be understood that the size of the generator may be increased or diminished, as the eXigencies of the case require, and the airinlet pipes may be increased in number accoi-ding to the volume of oil to be carbureted.

IOO

The oil supply and outlet may for the same reasons be increased or diminished as to their numbers as well as to the size of said pipes.

I have found by experiment that the oil when handled with my apparatus is not perceptibly affected by having a portion of the gas taken therefrom asit passes from the su p-` ply-tank to the overflow-tank through the apparatus, and no appreciable amount of oil is lost, thus virtually running the engine, which is especially adapted for pumping purposes, without noticeable cost and without lowering the commercial standard of the oil.

In operation oilis fed into the generator until it reaches the level of the overflow-pipe, when it will pass out through said pipe to the overflow-tank 6. When the required amount of oil is in the generator', the engine is started in the usual way by giving the fly-wheel a few revolutions, and after the engine has been started the effect of the reciprocation of the piston in the cylinderwill be to create a vacuum in the generator 2, thereby causing the outside air to bepdrawn in through the pipes 7 and 10,-which will pass through the loil, extracting therefrom the gas, which will pass out of the generator through the pipe 9 to the engine. In the drawings the heated-air connection is shown, and the air coming through pipe 1l would be heated; but it will be uuderstood that when the pipe 1l is disconnected from the pipe 10 the air at normal temperatnre will be drawn in through the upper end of the pipe 10 at the point where the union l2 now appears.

l. In an apparatus of the character described, the combination with a carburetingchamber having supply and overliow pipes leading into and therefrom, with a gas-drawoff pipe provided with a suitable valve, a-irinlet pipes adapted to be detachably connected with a heated-air supply, whereby heated air maybe delivered to said carbureting-chamber when the oil is stiff, and which when desirable may be disconnected from the heated-air supply, to supply air of the normal temperature as set forth.

2. In an apparatus of the character described, the combination with a suitable oilsupply, of a carbu reting-chamber, connections between the oi1-supply and chamber, an air-inlet pipe, an open-end oil-outlet pipe, a trap connected therewith, said trap being so formed as to counteract the vacuum in the generator and prevent'the admission of air to said generator through the trap, and a valve-con trolled gas-inlet pipe, substantially as set forth.

3. In an apparatus of the character described, the combination with a carburetingchamber having supplyand overflow pipes or channels leading into and therefrom, agasdraw-off pipeor channel communicating with the chamber and provided with a suitable valve, air-inlet pipes adapted to be det-achably connected with the heated-air supply, said pipe being adapted to deliver heated air to the oilfor the purpose set forth, and which, when desired, may be disconnected from the heated-air supply, to supply air of the normal temperature, as set forth.

4. In an apparatus of the character described, the combination with a suitable oilsnpply, of a carbureting-chamber, an air-inlet pipe entering said chamber near its bottom, connections between the oil-supply and the air-inlet pipe, an open-end oil-outlet pipe, a trap connected therewith, said trap being so formed that the iiuid therein will counteract the vacuum inthe generator and prevent the admission of air to said generator through the trapLand a valve-controlled gas-outlet pipe, substantially as set forth.
